Abstract: A method for producing a device for measuring current strengths. The method includes providing a resistor arrangement with two connection elements and a resistor element arranged between the connection elements, molding a contact element from the material of the connection element or from the material of the resistor element. The contact element has an end face remote from the resistor arrangement and a cavity open on the end face. The method further includes providing a circuit board with a through-bore on whose inner surface electrically conductive material is present, positioning the circuit board on the resistor arrangement such that the contact element projects into the through-bore, and expanding the contact element in the radial direction using an expansion element inserted into the cavity of the contact element to establish an electrically conductive connection between the contact element and the electrically conductive material on the inner surface of the through-bore.

Abstract: A resistor assembly including at least two connector elements and at least one strip-like or plate-like resistor element arranged between the connector elements. The resistor element has an upper side, a lower side and two longitudinal sides parallel to each other. The at least one resistor element is of a material of which the electrical conductivity is lower than the electrical conductivity of the material of the connector elements. The resistor element has, on at least its upper side or at least its lower side, at least one shaped element as a positioning aid.

Abstract: A resistor arrangement for measuring current strength having connection elements and a resistor element between the connection elements. The connection elements and the resistor element are arranged in a plane and in a row such that the arrangement is strip-shaped and has its smallest spatial extent perpendicular to the current direction. The resistor element has two contact sides and the connection elements each have a contact face connected to the contact sides. When current flows through the arrangement, current flow lines are formed which are deflected at at least one of the contact sides by an angle of at least 5° at the transition from the connection element to the resistor element.

Abstract: An arrangement of components for transferring electric current from a current-feeding component to a current-discharging component, including a first component, which feeds current to the arrangement or discharges current from the arrangement. The first component includes a first metallic material and, on at least one surface, has at least one spring lamella composed of the first metallic material and machined out of the first metallic material at the surface. The lamella is machined out of the first metallic material at the surface of the first component such that it is connected monolithically to the first component in a connecting region and, starting therefrom extends as far as a free end and, when deflected out of a rest position toward the surface of the first component, exerts a spring force directed away from the surface. A second component is in immediate contact with the lamella of the first component.
